1 Claim.

My invention relates to improvements in weather strips for windw's, particu1arly the lower sashes thereof.

The invention is designed with the particular purpose in view of: providing an 'inexpensive, easily, installed and durable weather strip for preventing rain, sleet and snow from beating in under the lower window sash.

' To the accomplishment of the above, and subordinate objects presently appearing, a preferred embodiment of my invention has been illustrated in the accompanying drawing, set forth in detail in the succeeding description, and defined in the claim appended hereto.

In said drawing:

Figure l is a fragmentary view in perspective looking at the window from theoutside thereof and illustrating my improved weather strip in.- stalled, and

Figure 2 is a fragmentary view in transverse section taken on the line 2--2 of Figure l and drawn to an enlarged scale.

Describing my invention in detail, with reference to the drawing by numerals, l designates theusual window casement, 2 the lower sash, 3 thelower sill of the casement and 4 the usual inside stool or ledge. I

According to my invention, a weather strip 5 A preferably of solid metal .and of the requisite length to extend across the casement l to the outside sash guides 6 is interposed between the bottom of the sash 2 and the sill 3, the bottom face of said sash 2 being rabbeted, or under cut, as at 1, along the outer edge of the same so that the top of said strip 5 seats in said rabbet 1..

The base of the weather strip 5 is flat and has i a pair of lateral flanges 8 and 9 extending along the outer and inner sides thereof for attachment, in a usual manner, as by nails, not shown, to the top face of the sill 3. The flange 9 on the inner side of said strip 5 is overlapped by the stool, or ledge 4. The inner side of said strip 5 is ver tical and straight, as at I, and fits flush against the outer edge of said stool 4 and similarly-against 4 ofsaid strip 5" inclines downwardly and outwardlyfrom the sash 2. A drain groove 12 is provided in the top of the strip 5 extending centhe rear face oftherabbet I. The outerface ll trally of said top along the entire length of the strip, said groove being V-shaped transversely and closed at its top by the under face of the rabbet 1 which extends preferably slightly beyond said top and outer face of the strip. As will be understood, the ends of the groove 12 are closed by the aforementioned sash guides. At suitable intervals the strip 5 is provided with V-shaped notches It in the upper front edge thereof communicating with the groove 92 and functioning as draining outlets leading from said groove to the outer. face i I of said strip.

s The manner in which the described weather strip 5 functions will be readily understood. Rain draining down the window sash 2 is shed at the M bottom thereof outwardly by the inclined outer face ll of said strip 5 and thus away from the bottom of the sash, and rain driving toward the window is prevented from beating in under the sash 2 and stool t by said strip. seepage which may occur between the rabbet l and top of the strip 5 is caught in the drain groove 12 and directed outwardly to the outer face H of the strip 5 by means of the drain notches l3.

The foregoing will, it is believed, suffice to im- 95 part a clear understanding of my invention without further explanation.

What I claim is:

In a window structure, a sill, a sash movable to open and to close the window opening and having a bottom undercut along its front edge, a stool cap section on said sill extending part way under said sash when the latter is closed, said section fitting flush against the bottom of said sash to said undercut and terminating in an outer vertical edge, and a bar-like weather strip extendin along said sill in front of said section for engagement of the sash therewith when closed, said strip having a vertical straight inner face fittingflush with the outer edge of said section and with the rearwall of said undercut, a fiat top fitting against the top wall of said undercut, and

' outer face inclining outwardly from said top,

the top of the strip-having a longitudinally extending channel therein and transverse drain grooves therein extending from said channel to said outer face of the strip.
